You can do the tax return yourselves, it’s not hard.
I would add one thing to scotlandx’s reply. To work out what is the best course of action do some sums.
1. How much could you earn in interest?
2. How much tax would have to be paid on that interest (30% of interest earned).
3. How much would it cost you to get your tax return done and lodged. Scotlandx is right it is easy and I would ring the tax office and ask for “Strata title body corporate tax return” (the tax office will post you at no cost) and have a look at it.
