Brisbane has separate domestic and international terminals connected by a 5-minute train or 20-minute walk. Connections between terminals require security re-screening, so allow at least 40 minutes minimum connection time. Use the train shuttle for faster transfers, especially during peak hours.

["Security re-screening required for all domestic-international connections adds 15-20 minutes","20-minute walk between terminals available but train is strongly recommended for tight connections","Limited real-time operational data on average security wait times makes tight connections risky"]

For shower access, try the Qantas International Premium Lounge in the International Terminal (near Food Court, level 4) if you have airline status or American Airlines Admirals Club membership—both offer showers at no extra cost. Otherwise, Plaza Premium Lounge near gates 81-82 provides both showers and spa facilities for pay-per-use access.
