Thought it would be worth noting to those who haven't yet lodged their 2018 income tax returns and intend to lodge it themselves, the deadline to lodge the return is tomorrow 31 October 2018.
If you are not ready to lodge your own return by tomorrow, you can either get an accountant to add you on their system so that you will get an extension or you can call the ATO directly and explain your extenuating circumstances and hope to get an extension.
just call ato ask for extension, they gave me till 15 december 2018 (lodging without tax agent), easy peasy
