For those cheapskates amongst us who may be interested, the 400 bus (Burwood to Bondi via the airport) is now split into 2 runs.
The 400 does the Eastern suburbs side only - Bondi>East Gardens>Mascot>Domestic>International.
The 420 & 420N do the old Burwood to International>Domestic run.
The stands (or stops) in Burwood remain the same.
Here are the stand numbers if you want them:
Burwood - To Airport (Stand F): 213434 (420/420N)
Burwood - From Airport (Stand E):213451 (420/420N)
International Terminal: 202015 (400/420/420N)
Domestic Terminal: 202067 (400/420/420N)
