A "starstruck" Brisbane mum dressed in her PJs has snapped a selfie with Pirates of the Caribbean star Johnny Depp, dressed as Jack Sparrow, after he singled out her daughter in a small gathering at Raby Bay.

Kaylynn Maree said upon seeing internet rumours this morning that the cast and crew of Pirates would be filming at the marina, she hurriedly dressed daughter Chelsea and went to the makeshift set.

The Redlands resident and about five other likeminded fans struck gold when Depp, 51, walked by in full Sparrow make-up and costume

"We were still a bit starstruck," Ms Maree told ABC 612 Brisbane.

"I woke up at 7am, got my child dressed, didn't worry about myself and said 'alright let's go'," she said.

"We came straight here and waited in the cold for an hour and finally got to see him. I didn't expect him to come up close to me."

Filming for the fifth instalment of the popular Pirates movie franchise has been underway in south-east Queensland since earlier this year, most of it on the Gold Coast.

Depp made headlines around the world last month when he was caught out bringing pet dogs Boo and Pistol into the country without declaring them to quarantine.

Agriculture Minister Barnaby Joyce said the dogs could be put down if they were not taken back to the US.

The puppy pair eventually fled the country on Depp's private jet days later.

Return trip after rumours of Orlando Bloom sighting

Ms Maree said she could not remember much about the encounter, but it felt very authentic.

"We saw his hat, he was all dressed up. He was in character, he even sounded like Jack Sparrow when he spoke," Ms Maree said.

"He came up to my daughter. He was waving at her and came up towards us.

"I don't remember what I really said, it was too much of a 'what the heck'. He came up to her and we went to take a picture but he was being ushered on.

"There wasn't a chance for a proper photo, so it was a selfie."

Ms Maree said she and Chelsea were back at the marina this afternoon following rumours Orlando Bloom, who has previously starred in the Pirates of the Caribbean film series, would be on set.

"We'll see what happens," she said.
