Sydney office workers have let off some steam while hitting the town for their annual Christmas parties.
While some revellers donned formal attire for Friday night's celebrations, others took advantage of the occasion to pull out some of their wackiest costumes.
Many were seen in Christmas-themed outfits including one man in an elf costume, while one group of women dressed as Harry Potter characters.
Party-goers took advantage of the warm weather with dozens embarking on boat trips around the harbour.
Barangaroo was a major hot spot with the area filled with glammed-up workers ready to let their hair down, as was The Rocks and Hyde Park.
Some revellers were seen looking a bit worse for wear as the night came to an end and there's sure to be some sore heads in the morning.
