The Hottest Halloween Party in Sydney's Celebrity Scene

Reality TV stars of Australia set the red carpet on fire at Believe Advertising & PR's 22nd Birthday Bash on Saturday night. The event, known as the most anticipated Halloween party in Sydney's celebrity scene, saw the who's who of reality TV descend upon Susstudio in Kings Cross.

Leading the arrivals was Olivia Frazer, known for her appearance on Married At First Sight, who turned heads in a sexy Marie Antoinette inspired ensemble. Her pink corset-style top, cage hoop skirt, and white fishnets perfectly embodied the spirit of the night. Olivia completed her look with pink heels and dramatic makeup featuring pink blush and a faux beauty spot.

Emma Roche from The Bachelor and Steve Pliatsikas from The Bachelorette also made an impression. Emma embraced the Sporty Spice persona, looking effortlessly cool in a black mini dress and chic sunglasses. Steve paid homage to David Beckham, donning the famous Manchester United uniform and clutching a football.

Samantha Harvey, another star from Married At First Sight, dared to bare in an angelic white top paired with revealing shorts. Melissa Sheppard, also from MAFS, made a memorable appearance by donning the wedding dress she wore on the show, accentuated with a gothic-inspired bouquet.

Carolina Santos, yet another MAFS bride, caught attention with her eye-catching silver angel costume, complete with large wings and a halo headband. MAFS couple Melissa Rawson and Bryce Ruthven showcased their creative sides with distinctive costumes: Melissa as Freddy Kruger and Bryce as Squid Game's player 456.

Nasser Sultan, a MAFS groom, played it safe by wearing a large evil eye necklace to ward off any bad spirits. The party also brought together Melissa Lucarelli from MAFS and Below Deck's Hannah Ferrier, both sporting retro roller derby inspired looks.

Actress Clare McCann wrapped up the glamorous event by channeling the Statue of Liberty.

The party was a true feast for the eyes, with reality stars showcasing their creativity and style in a range of costumes. Believe Advertising & PR's 22nd Birthday Bash certainly lived up to its reputation as the hottest Halloween party in Sydney's celebrity scene.
