The newlyweds were spotted by locals earlier this morning.
One lucky Sydney-sider, Steven Beale, spotted the loved up pair on Wednesday as he was walking to work just after 8am.
"I walked past her at the foot of the Harbour Bridge with her husband and, I think, a personal trainer," he told Fairfax Media.
The 33-year-old was glowing, smiling ear-to-ear, donning a chic black blazer, black and white striped dress teamed with a cute pair of espadrilles.
Meanwhile, James looked very relaxed in a blue jumper and pair of jeans.
The duo are reportedly staying in a waterfront hotel, getting the best seat in the house for Sydney's Vivid Festival.
Duchess Catherine's little sister and her billionaire beau had reportedly flown into Sydney Airport from New Zealand late last night.
The couple seem to have zero jet lag, with onlookers spotting them out and about on a water taxi in Sydney Harbour taking in the stunning sights.
James and Pippa's May 20th whirlwind wedding extravaganza included a stunning ceremony, which saw Prince George and Princess Charlotte reign as page boy and bridesmaid, followed by two wedding receptions.
Obviously, after such celebrations a holiday is needed.
And the newlyweds have been zipping across the globe in wedded bliss.

Pippa and James traded in the British countryside, kicking off their life as husband and wife in French Polynesia.
The pair stayed as at an friendly resort is called The Brando which is located on the island of Tetiaroa.
The private island is a favourite with celebrities, and previously hosted Michelle and Barack Obama earlier this year for their post-presidency holiday.
According to the resort's website, a one-bedroom villa for two people will set you back a minimum of $5000 per night.
For something more spacious, a three-bedroom villa costs about $14,000 per night - that price includes breakfast!
