Swim Thru Rottnest 2021 (expired event)

For its 45th year, the annual Swim Thru Rottnest takes to the shores of Rottnest Island on the 4th of December.

Get the whole family involved and choose from a 500m or 1600m swim in the crystal clear protected waters of Rottnest Island. The 500m Swim will start all at once. Starting waves may be used depending on the number of entries. The 1600m Swim will have colour coded caps issued at Registration to determine your starting position. Swimmers will be sent off in waves of 3 minute intervals and no more than one colour will be allowed in the water at any one time.
