[2] It is not in issue that, between July and October 2013, the first respondent, Hippo's Concreting Pty Ltd ("Hippo's") performed construction works for the benefit of the applicant, Eco Steel Homes Pty Ltd ("Eco Steel") on projects at South Pine, Dakabin and Urangan. The works comprised, in the majority, concreting and block work. Hippo's rendered tax invoices to Eco Steel. Eco Steel did not, however, pay all those tax invoices. It disputed that it had a contract with Hippo's for the performance of the works. The basis for the contention that there was no relevant contract between Eco Steel and Hippo's is opaque. Hippo's was retained to undertake these works by one Brendon Corrie, who was described as the 'construction manager' for 'Eco Steel Homes' in email and other correspondence, and who utilised what appears to be Eco Steel's logo in his correspondence. There is no suggestion that, at the time Hippo's performed the works, Eco Steel disputed Mr Corrie's authority to retain Hippo's. On the contrary, as was properly conceded before me by counsel for Eco Steel, Eco Steel retained the benefit of the works performed by Hippo's on Eco Steel's projects. It was also the case, as was conceded by Eco Steel's counsel, that Eco Steel in fact paid at least for part of the works performed by Hippo's at the request of Brendon Corrie.
