I dont know about etax.com.au, but Etax is the ATO's own tax return program. You download it from the ATO, fill in your info and when you lodge your return, it connects to the ATO and submits the info. Most of the data is stored in a file on your own computer. It's pretty easy to do, tells you if your answers mean you don't qualify for certain sections so you don't waste time trying to figure it out. Even medical and rental properties are easy enough. I used it every year until I got a Mac, but the ATO only do it for PC.
Thank you shmach.
Sorry for not being clear in my first post. I knew about etax (etax.com.au probably should not been allowed to use the name of government's software as a name for a commercial web site, but it is a bit of a gray area, where I should admit, not and expert of) program and have used it to lodge the taxt return in a previous years.
This year though, I expect the tax return to be a more complicated and thus I seek a help of an accountant. I called a few accountants in our area and even though they said they could do the return over the email (as I won't be able to meet them within a reasonable working hours anyway) they were not able to explain (probably because they don't practice it much) how exactly should I send the tax related information to them (a spreadsheet summary, or each receipt, etc).
So I went to check for online tax return services, whom I would expect to be experts in doing tax returns via internet and email, but the very cheap price (three times cheaper I got quoted by an accountant) and no credible reviews got me thinking about the quality/suitability of their service.
