Wherever a bicycle lane is provided as part of a carriageway, and is in a reasonable condition for use, a rider of a bicycle shall use that portion of a carriageway and no other.
It has to be said that a bicycle lane is defined by bicycle lane start and end signs. There are precious few of these in Perth!
Here's another part of the WA RTA that seems to prohibit riding two abreast;130. (1)Riding 2-wheeled vehicle alongside more than one other rider
The rider of a motor cycle, moped, power-assisted pedal cycle or bicycle shall not ride on a carriageway that is not a multi-laned carriageway alongside more than one other rider, unless the rider is overtaking the other riders.
That prohibits three abreast not two abreast.
