Introduction
The Senior Investigator at NSW Fair Trading leads compliance and enforcement work in the rental market. These ongoing roles sit in the Investigations & STRA team, with a focus on shared housing, boarding houses and the Short-Term Rental Accommodation Code of Conduct. The work involves serious and systemic non-compliance, so applicants need to explain how they investigate risk, build reliable evidence and make defensible enforcement decisions.
This guide explains how to apply for Senior Investigator and organise examples relevant to that regulatory setting. Your application should make the reasoning behind your decisions clear: how you assessed the potential harm, what evidence you obtained and why the action you recommended was appropriate. View the official job ad and read the role description before choosing your examples.
The vacancy notice does not specify the application documents. We recommend preparing a tailored two-page cover letter and an updated resume, then checking the application form for the required uploads and any response limits. Treat that preparation advice as a starting point and follow the actual form instructions when you submit.
