When you have arrived at the venue, open the Motorsport Australia App and select the 'Check-In' button on the bottom right of your screen.

You will then see the name of the event and venue you are located in.

When Check-In has opened, as determined by the event organiser (the time and date for this should be in your Supplementary Regulations), tap the 'Check-in Now' button.

An alert will then appear informing of your successful check-in. Once this is complete, you have signed-on for the day and you are ready to compete.
