My experience was the opposite with investment property accountant in Sydney (6 years ago). Accountant was referred to us ( after first return, he passed our portfolio to underling accountants in the office) to do our 1x property investment then 2 when we moved overseas. I owned 1% of no. 1 property and 50% of number 2, but thought I had a tax free threshold.

Decided to do my tax 2 years ago and found out no tax free threshold with being non-resident. Had to lodge 3 x previous returns for myself as my husband’s was the only lodgement the accountant had prepared. Then I had to back pay with interest (no fine as yet!)
Now do tax myself. I tried to ‘have it out’ with the accountant but it’s hard when you are just talking on the phone from o/s.
Yes, it’s time consuming, very!

I don’t know where you find a great one, maybe the people on this site can help you. IMO, you should request/tell them never to pass your tax portfolio onto another accountant in the office.

Or maybe get yourself some good software. The US has some awesome tax software, so maybe some Oz companies are developing some or have. I am going to follow this up later, so I’ll let you know if I find some. Or if anyone knows of any good Australian tax property investment software to buy, then give us a holla!

As I’m not a huge investor, I can’t offer any other advice.
Good luck.
