Raby Bay couple fast-tracks wedding at The Courthouse to be wed by Queensland's 4pm COVID-19 lockdown on Saturday

Raby Bay couple Nicolette and Sam Brewer's wedding was scheduled for 3.30pm at The Courthouse Restaurant last Saturday when the state government called its snap 4pm delta COVID-19 lockdown.

In a mad scramble, the couple brought the wedding time forward to noon in an effort to have the big event all tied up by the time the lockdown arrived.

Ms Brewer said they were already getting ready for the big day when the news broke, turning the day into a whirlwind.

"Wedding manager at The Courthouse Carol Balfour called me and asked me what we wanted to do... We agreed to move it forward and she made it happen," Ms Brewer said.

"We didn't expect a lockdown, but Sam and I agreed it was important to just get married anyway."

Vendors, hair stylist and makeup artists sprang into action.

The Brewers remained calm, and with 66 people on the guest list, this was no mean feat.

"My two bridesmaids contacted guests and Sam called family... Only nine guests couldn't make it," Ms Brewer said.

"The list was originally 84 guests, but some could not fly in from New Zealand, WA and Melbourne."

The couple have been engaged since February and had been planning their special day for the past three months.

Courthouse owner Mary Gibb said the Brewers outlook was positive and loving.

"We are thrilled the wedding could go ahead, and only for the hyper vigilance of announcements were we able to respond as quickly and mobilise everybody as quickly, from the couples wedding suppliers, to our teams of kitchen and service staff," she said.

Ms Gibb said the wedding party was supported by family and friends, and a random group of people who had gathered for breakfast near the water at the end of Paxton Street, who jumped in to help set up the garden.

"We had our reception and got to have a first dance and speeches until we had to shutdown.

"Plans for our honeymoon on Straddie have been put on hold for now," Ms Brewer said.
