There are many methods to try using - my background is mostly in IT,
HR, Banking and Finance recruitment...
1. Job Boards - there are many out there, and some free that work quite well. Specifically for Accounting/Finance have a look at
http://www.seek.com.au
http://www.mycareer.com.au
http://www.efinancialcareers.com.au
http://www.nowhiring.com.au
and of course - YOUR OWN WEBSITE - post your roles on there too!
2. The newspaper such as MyCareer in the Age or other papers is like throwing your money down the drain - you could pay up to 5-10k for a block colour advert. Unless this is a very big paying role, you are wasting money.
Knowing many accountants, most of them are smart enough to look online, and also in their own trade organisations magazines, CPA/CA/Tax etc etc
