If you fall short points-wise but have time on your side, you might consider applying for jobs in the UK with companies that have cyber roles in both UK and Australia, then try and transfer internally. A lot of global firms will have tech hubs in EMEA, US and APAC so they can provide round the clock support.
Quite a few Aussie banks have cyber roles in London, e.g., Westpac, Commonwealth Bank and Macquarie.
