I haven't seen an announcement for this year, however last year their schedule was:

Vanguard Personal Investor annual tax statements will be issued in two tranches

Investors holding Vanguard Managed Funds only – Tuesday 2 August 2022
Investors holding Vanguard Managed funds and/or ETFs and/or Direct Shares – Thursday 18 August 2022

Annual investor statements issued – Monday 12 September 2022

So I imagine you should hear something from them over the coming months.
