Basis for opinion
We conducted our audits in accordance with Australian Auditing Standards. Our responsibilities under those standards are further described in the Auditor’s responsibilities for the audit of the financial reports section of our report.
We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.
Independence
We are independent of the Group, THT and TIL in accordance with the auditor independence requirements of the Corporations Act 2001 and the ethical requirements of the Accounting Professional & Ethical Standards Board’s APES 110 Code of Ethics for Professional Accountants (including Independence Standards) (the Code) that are relevant to our audits of the financial reports in Australia. We have also fulfilled our other ethical responsibilities in accordance with the Code.
Our audit approach
An audit is designed to provide reasonable assurance about whether the financial report is free from material misstatement. Misstatements may arise due to fraud or error. They are considered material if individually or in aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of the financial report. We tailored the scope of our audits to ensure that we performed enough work to be able to give an opinion on the financial reports as a whole, taking into account the geographic and management structure of the Transurban Group, THT and TIL, their accounting processes and controls and the industry in which they operate.
Audit Scope
Our audits focused on where the Transurban Group, THT and TIL made subjective judgements; for example, significant accounting estimates involving assumptions and inherently uncertain future events.
In establishing the overall approach to the Group audit, we determined the type of work that needed to be performed by us, as the group auditor, or component auditors from other PwC network firms operating under our instruction. Where the work was performed by component auditors, we determined the level of involvement we needed to have in the audit work at those components to be able to conclude whether sufficient appropriate audit evidence had been obtained as a basis for our opinion on the financial reports of the Transurban Group, THT and TIL as a whole.
