the full amount of the premium (in the case referred to in paragraph (a)), the balance of the premium unpaid or, where no instalment has been paid, the full amount of the premium (in the case referred to in paragraph (b)) or the amount of the adjustment (in the case referred to in paragraph (c)) together with a late payment fee calculated at the prescribed rate may be recovered as a debt in a court of competent jurisdiction."
22 In Employer's Mutual Indemnity (Workers Compensation) Ltd v A Donald Pty Ltd [1997] NSWSC 102, his Honour Cole JA, (with whom Priestley and Stein JJA agreed), held as follows:
"The provisions of the Act and regulations to which I have referred make plain, to my mind, that the legislature intended to and has established a regime whereby the quantum of an insurance premium is to be determined in the first instance by the insurer in accordance with an insurance premiums order pursuant to s.169. If the employer is dissatisfied with the premium so calculated and sought by the insurer, the employer's rights are to apply pursuant to s.170, and in accordance with the regulations, to the Authority to determine the correct premium. If the premium as determined by the insurer is not so queried or challenged, or if after challenge the premium is determined by the Authority, that is the premium which the employer must pay. It is that premium which is recoverable pursuant to s.172 by the insurer, or if there be an overpayment resulting from a redetermination by the Authority, recoverable by the employer pursuant to s.170(4). Whilst it may be possible, perhaps, to challenge by way of administrative review an asserted error of statutory application of the formula (a matter which it is unnecessary to decide), the legislature has, in my view, made clear that any factual determination in application of the statutory formula for premium determination is not a matter for review within the courts but is to be determined by the Authority.
