Am I an Australian resident for tax purposes - WHV

I'm on my first WHV 417 Visa in Australia, having moved from the UK. The tax year here obviously runs to the end of June. I only moved over here in Feb, but the info I've repeatedly searched on ATO (yes I have used this a lot), says I should be considered an Australian resident for tax purposes. I still am questioning this, hoping someone else has done similar on their tax return (rather than just ticking working holiday maker) because:

- I have only been here since February, so less than 6 months (183 days) of the tax year

However:

- I have moved here for the purposes of finding employment, living with my spouse (moved same time, British) and a better quality of life

- I signed up to a 6 month rental contract from 1st March

- I have worked for the same employer since 3rd March and will be applying for an exemption to allow me to stay with them longer

- I have no physical assets in the UK, just savings accounts

Thanks
