A couple of initial thoughts...
As you look to transition your assets into super, you might want to check whether you and/or your partner are eligible to Carry-Forward Concessional contributions, and if so, how much? You can find that from the ATO Super section in MyGov. It might be worthwhile doing so if you can prior to your super balance hitting $500k (I'm pretty sure the carrying-forward of concessional contributions stops once your balance is more than $500k).
I think your travel budget is going to be waaaay more than you need, based on what you've previously told me you're looking to do. I appreciate that you're thinking of this money partially as a buffer though.
From your spreadsheet:
Once your super account enters pension mode, you have to draw down a minimum amount every year (
https://www.ato.gov.au/Rates/Key-superannuation-rates-and-thresholds/?anchor=Minimumannualpaymentsforsuperincomestrea#Minimumannualpaymentsforsuperincomestrea). Note that this minimum amount was halved during the pandemic years, so it's likely to go back to 4% for 60 year olds at some point in the not too distant future. You can draw down more if you like. Note that 'drawing down' doesn't have to equate to 'spending it', it just means that it comes out of the tax advantaged environment.
Once you enter pension mode, you can receive your payments at a regular period. I think this depends a bit on your super fund, but if you were with HostPlus, for example, you could receive payments fortnightly, monthly, quarterly, half-yearly or yearly. You could
possibly optimise by choosing to draw down annually at the end of the financial year and then use that money for the upcoming year, but that seems like hard work for only a small amount of upside to me. Mrs G and I are going to draw down monthly from our accounts when the time comes.
You should be able to claim a tax deduction for any personal concessional contributions. And you will have a bit of tax to pay between your IP, your Vanguard distributions and any CGT as you sell down your Vanguard fund.
Don't know much about insurance bonds.
