The Perth Royal Show will include a walk-in vaccination clinic where all West Australians aged over 12 will have access to the Pfizer vaccine when it kicks off this Saturday.

Entry to the show will be discounted by 25 per cent and capped at 60,000 people per day.

It comes as the state opposition pointed to vaccine hesitancy and complacency, not supply, as the main issues now facing the Western Australia rollout.

Just over 41 per cent of the WA population are fully vaccinated, putting the state equal last with Queensland.
