When Brits travel to Australia they can use e-gates, but the same courtesy is not extended back to us.
Sure can. When I flew to Brisbane, no human inspected my paperwork. From plane to train, the only human interaction was someone taking a stub of something that came out of a machine and waving me through. Really smooth.
As an Aussie this pisses me off entering the UK. When Brits travel to Australia they can use e-gates, but the same courtesy is not extended back to us. Frequent travellers can pay to use the gates, but not everyone has that option. If the strategy is to use the gates they should make them as available as possible.
