I have citizenship for Australia, UK & Ireland, and possess a passport for each and am planning a trip for this year. Please can you help me understand the best way to travel on these if I'm travelling from Sydney to London to Dublin, then Amsterdam, London, Sydney. It's a little complicated and I'm tempted to simply travel on my AU passport only as that's where I live and my other two passports are currently blank.
Any advice would be appreciated! Thanks.
