Yes — UK passport holders need an Electronic Travel Authority (ETA) subclass 601, free for British citizens via the Australian ETA app (AUD 20 service charge). Valid 12 months, each visit up to 3 months. Apply before flying — airline won't board you without it. Passport must be valid for duration of stay.
Singapore — only 7h flying time to Sydney, excellent airport (Changi), and a great 2-3 night stopover city. Dubai + Doha are both 14h to Sydney (very long second leg). Hong Kong (Cathay) is 9h 30m second leg, and a solid 2-night stop. Most travellers pick their layover by airline loyalty and airport lounge quality.
4-5 days minimum. After 22h of flying and crossing 9 time zones, jet lag needs 2-3 days to settle. Sydney's main sights (Harbour Bridge, Opera House, Bondi, Manly, Blue Mountains) need 3-4 days. If flying this far, many people add Melbourne, Cairns/Reef, or New Zealand — 2 weeks minimum for a full Australia trip.
