Bank the 800k and leave alone.
Then during the same year keep depositing 65K+ monthly. (12 deposits)
Come renewal time you will have evidence to either remain on the 800k deposit or change to the monthly route to justify your first extension.
The choice is yours.
You will earn practically no interest on your 800k so it's probably better to reinvest that elsewhere if you choose the income route.
