Australian Dual Citizens Entering UK after February

[skittle]

On that British Nationality Act website, for UK citizens living abroad there are repeated mentions about registering a minor. Therefore, if a UK citizen living in Australia does not register their child for dual citizenship, there is no need for that child (or subsequent adult) to tick the dual citizen box on the ETA application. Their Australian passport, after all, clearly shows their birth place being a city in Australia.

I think this could still be a problem. My son is 19, technically a dual citizen due to me but has never had a uk passport and was born here. He travelled to the UK last year with an ETA fine but without me.
If we travelled together it would be clear that he is a uk citizen because my passport shows my birth place too, and could be refused.

I also wonder if there could be other repercussions if he subsequently applies for a British passport or wants to move there with records of using an ETA. Especially after Feb where you would effectively have to lie on the application.
I struggle to understand the benefit that the UK is receiving by forcing British citizens not to use the ETA. Sell a few more passports? Harvesting info on British citizens overseas?

The obtaining of new passports will probably blow out like it did when travel recommenced after COVID. There will be a plethora of applications, which will take far longer than usual to process. Which means more anxiety and complaints.

Going back in June, will need to renew the UK passport as they are expired. I hope the queue isn't too long.
