Queensland police shut down three house parties in the 24 hours after some coronavirus restrictions were relaxed, issuing infringement notices twice at the same residence.
Chief Superintendent Mark Wheeler said police attended the same Carrara property twice over the weekend, issuing 25 fines to people having parties.
"Really, really disappointing that these two incidents at the one address have yielded some $33,000 in fines," Chief Superintendent Wheeler said.
"The people involved have shown a blatant disregard for the Chief Health Officer's directions."
Police Commissioner Katarina Carroll said overall Queenslanders had behaved well over the weekend, with some exceptions.
"I think we should continue with this, however if we have the blatant disregard, and a lot of it, it will jeopardise what we're trying to achieve," Commissioner Carroll said.
"I think Queenslanders have done amazing this weekend — there were a lot of people out."
In Brisbane, officers were called to a party in Banyo on Saturday and charged five women and four men, all aged in their early 20s, who were celebrating a birthday in a small unit on Tufnell Road.
More than 900 officers worked across the state to ensure the public were enjoying their new freedoms appropriately.
On the Gold Coast, police dispersed crowds at Burleigh Hill prompting concerns from locals.
Chief Superintendent Wheeler described the large crowd as "really unfortunate".
"That group of people was far too large for the area they were in," he said.
"I've since asked City of Gold Coast to install some barriers and some signage, we will increase our police presence there this afternoon, and this evening and we will not be so tolerant on this occasion.
This afternoon Queensland police installed fencing at Burleigh Hill and erected signs reminding people to physically distance.
Local resident Robyn Porter said she didn't think people would take notice of the new signs.
"I was pretty annoyed, I do believe that during this social distancing if you do go somewhere and it's already full you need to turn away and go somewhere else," she said.
"There is more distancing (today), which surprises me… I almost expected to see it like yesterday and wondered if we would even be able to stay here."
Nicole Simpson spent Monday having a picnic with her family at Burleigh Hill, and said she saw the footage of crowds from the day before.
"I was happy everyone was out having fun and enjoying themselves," she said.
"They weren't social distancing, they weren't doing the right thing by the government standards … but I think they were doing something great for themselves, getting out, enjoying nature and the environment."
Queensland Chief Health Officer Jeannette Young said she was pleased "the vast majority" of people had been careful over the weekend.
Dr Young said there had been three new COVID-19 cases confirmed overnight and testing rates had fallen most likely due to the low overall rate of respiratory infection across the state.
"Could anybody who's feeling at all unwell please go and get tested," Dr Young said.
