As at the time of this post writing there are no Covid restrictions on weddings in Perth except for the usual sign in with proof of vaccination. Straight from the WA Government website:

Capacity limits

There are no longer any capacity restrictions for venues and events. This means private gatherings, concerts, and weddings can go ahead at full capacity.

Measures remain in place to keep these events safe:

Be safe assured that Caversham House complies with the above requirements. Please have your valid Covid vaccination certificate with you when you join a wedding party at Caversham House.

Our staff practice the highest level of hygiene.

Mask Wearing Rule Perth

Mid-February 2022: The mask-wearing rule is still in force but not while eating our delicious local food and drinking premium wine from our nearby Riverbank Estate winery.

With vaccinated wedding guess, especially at our out door weddings in Perth’s Swan Valley, the chances of contracting covid is VERY remote.
