Airport Link (T8 Line): $20.67 peak/$17.87 off-peak one-way to Central using Opal (includes $14.87 station access fee plus regular T8 fare). Runs every 10 minutes, 15 minute journey direct to Central Station with connections to all Sydney train lines.

Taxi: $60 flat rate to CBD during NSW trial period, but journey time varies wildly depending on Eastern Distributor traffic and weather conditions affecting tunnel closures.

Rideshare: $40-55 normal times but surges to $90+ during peak/weather when Harbour Bridge or tunnel delays kick in.

T8 Airport Link is clear winner for solo travelers heading to Central, Town Hall, or Circular Quay. Groups of 3-4 people heading directly to Bondi or Manly, taxi becomes competitive especially with luggage considerations since you'd need bus transfers anyway.
