THAWLEY J:
1 AEI Insurance Group Pty Ltd is a heavy motor transport broker. It employed Mr Craig Martin as an account manager in a business development role from 10 July 2011 until about 2 September 2022. Mr Martin resigned on 29 August 2022.
2 Mr Martin entered into a written contract of employment on 1 November 2020. Clause 12(c) provided:
12. Restraint
The Employee must not either directly or indirectly:
…
(c) during their employment with the Company and for the Restraint Period, solicit, canvass, deal with or approach or accept any approach from any person or organisation who was at any time during the last 12 months' [sic] of the Employee's employment a client or customer of the Company in that part or parts of the business of the Company in which the Employee was employed and with whom the Employee had dealings with or influence over, with a view to obtaining the business of that client or customer in a business that is the same or similar to or in competition with the business of the Company;
3 The "Relevant Period" is defined in the following terms in clause 12.7(b) of the contract:
Relevant Period means each of the following periods commencing from the termination of the Employee's employment:
(i) 12 months;
(ii) 9 months;

4 Clause 13.1(a)(i) of the contract provided:

(a) all trade and business secrets, other confidential information and any documents (in whatever form, however stored, and including copies and extracts) relating to the affairs and business of the Group or which the Employee acquired in the course of their employment with the Company, whether or not originally supplied by a Group Company, including the following:

(a) they must only use Confidential Information for the purpose of performing their duties for the Company under this Agreement;
(b) during the Employee's employment and thereafter, except in the proper course of their duties, the Employee will not use or disclose to anyone any Confidential Information, and will use their best endeavours to prevent unauthorised use or disclosure of the Confidential Information by third parties, unless required by law;
6 Clause 15.6(e) of the contract, under the heading "What happens on Termination", provided that: "the Employee's obligations under this clause, and clauses 12 and 13 continue after termination".
7 On 8 November 2022, AEI commenced proceedings against Mr Martin alleging, amongst other things, that Mr Martin breached clauses 12(c) and 13.2(a) and (b) of the employment contract. It is also alleged that Mr Martin breached s 183 of the Corporations Act 2001 (Cth), which relates to the improper use of information obtained by an employee in the course of his or her employment.
8 AEI also sought interlocutory relief in the nature of an injunction restraining Mr Martin from breaching the provisions of his employment contract earlier mentioned. Justice Wigney made orders granting interlocutory relief on 9 November 2022: AEI Insurance Group Pty Ltd v Martin [2022] FCA 1384. In his reasons, Wigney J summarised the evidence of AEI's director, Mr Michael Donaldson, in the following way:
15 … During the course of his employment, Mr Martin had access to client details, developed close relationships with clients and was made aware of business opportunities. He was provided with a mobile phone and laptop computer and was able to log into AEI's client management system. He was paid a relatively sizable base salary.
16 Mr Martin notified AEI of his resignation on 29 August 2022. He initially declined to indicate what his intentions were in terms of future employment, but eventually admitted that he would be working for one of AEI's competitors, MA Insurance Brokers. AEI subsequently diverted to Mr Donaldson any calls that were made to the phone that had been provided by AEI to Mr Martin.
17 Shortly after Mr Martin's resignation, Mr Donaldson sent Mr Martin an email which reminded Mr Martin of his obligations under the employment contract in relation to confidential information and restraint.
18 On 5 September 2022, Mr Donaldson became aware that a text message had been sent to one of AEI's clients. That text message provided information in respect of Mr Martin's new phone number. When Mr Donaldson became aware of that text, he caused AEI to write to Mr Martin and again draw his attention to clauses 12 and 13 of his employment contract. Mr Martin responded to that communication through his solicitors.
19 Further correspondence ensued between AEI and its solicitors and Mr Martin or his solicitors. In the course of that correspondence, Mr Martin's solicitors confirmed that Mr Martin had sent a text message advising of his new mobile phone number to all of his contacts, including family and friends. The problem was that Mr Martin's contacts also included the clients with whom Mr Martin had dealt while he was employed by AEI.
20 In early November 2022, Mr Donaldson became aware that a sizable number of AEI's clients had withdrawn their business from AEI and engaged with MA Insurance Brokers. The business conducted by MA Insurance Brokers was similar to the business conducted by AEI. They were competitors.
21 Mr Donaldson, along with some other officers or employees of AEI, subsequently contacted the clients who were believed to have shifted their business from AEI to MA Insurance Brokers. They asked the clients why they had shifted their business to MA Insurance Brokers. The results of those enquiries were summarised in a table annexed to Mr Donaldson's affidavit.
22 The enquiries revealed, in summary, that the clients had shifted their business to MA Insurance Brokers as a result of the fact that Mr Martin had moved to MA Insurance Brokers. Some of the clients confirmed that they had been contacted by someone at MA Insurance Brokers and told that Mr Martin now worked there. At least one of the clients indicated that he had had a conversation with Mr Martin after he had moved to MA Insurance Brokers. A number of the clients indicated that they had had no adverse issues with AEI and had had no contact or dealings with MA Insurance Brokers prior to the shift of their business.
23 Mr Donaldson claimed that 21 former clients of AEI had moved their business to MA Insurance Brokers following Mr Martin's relocation there.
9 The parameters of the case are now defined by an amended originating application and statement of claim filed on 8 December 2022.
10 Since his resignation, Mr Martin has retained a mobile telephone purchased by AEI for the purposes of undertaking his employment duties with AEI (AEI Mobile). This is an Oppo AX5 Android Smartphone with International Mobile Equipment Identity Number 862877040284760. AEI has unsuccessfully requested the return of the AEI Mobile from Mr Martin on several occasions. AEI has retrieved a laptop used by Mr Martin in his employment with AEI.
11 As Wigney J noted in his reasons at [18], on 5 September 2022 a text message was sent to various clients of AEI providing Mr Martin's new mobile number. AEI says it has been unable to determine whether the text message, presumed to be sent by Mr Martin on 5 September 2022 was sent from the AEI Mobile or another mobile device.
12 AEI submits that the text message demonstrates communication by Mr Martin with clients and the presence of a new mobile phone or a new mobile phone number.
13 On 30 November 2022, orders were made for standard discovery to occur by 28 January 2023. On 22 February 2023, Mr Martin served his List of Documents. The List of Documents nominated only one item, being the laptop owned by AEI which AEI had recovered on 7 November 2022. There was no discovery of any other document, including the text message sent on 5 September 2022.
14 On 2 March 2023, AEI's solicitors obtained access to documents produced pursuant to approximately 41 subpoenas which had been issued to various insurers and former clients of AEI that had appointed MA Brokers. Those subpoenas had been targeted towards obtaining information relevant to former clients of AEI who had transferred their business to MA Brokers since the resignation of Mr Martin.
15 By an interlocutory application filed on 10 March 2023 amended today, AEI seeks orders:
that Mr Martin provide "further and better discovery" or, alternatively, discovery in various articulated categories; and
under rr 14.01 and 20.21 of the Federal Court Rules 2011 (Cth) (Rules) for delivery up and examination of the AEI Mobile and any other mobile which used a specified mobile number (being the new number Mr Martin had advised about in his text message of 5 September 2022), together with various consequential orders.
16 AEI relied on the following affidavits in support of the orders sought:
Mr Michael Donaldson, a director of AEI, sworn on 28 February 2023;
Mr Adam Daniel, a Forensic IT Manager at KPMG Australia, affirmed on 6 March 2023; and
Mr Lachlan McBride, one of AEI's solicitors, sworn on 10 March 2023.
17 The material produced under subpoena was reviewed by Mr McBride. His affidavit reveals that Mr Martin was copied to various emails to or from former clients of AEI and also that he exchanged some text messages with former clients.
18 Documents produced pursuant to a further three subpoenas became available to AEI's solicitors on 16 March 2023. The documents were produced by CGU Insurance, Neven's Haulage and JVB Transport. It was submitted that those documents also included correspondence between Martin and the former clients of AEI including a chain of text messages. However, no evidence in this regard was adduced.
