Could controversial former Auburn deputy mayor Salim Mehajer be planning a change of scenery?

A week after stealing the show at his sister Kat's opulent Sydney wedding, he is hinting at leaving the country.

Mr Mehajer posted a picture of a ship on Sydney Harbour with the caption, "Goodbye Australia" on his Instagram page on Saturday.

"Will be taking off to pursue my dream challenges," he wrote, adding: "I'll be back."
