The 52-year-old was spotted with brunette Emma Goody earlier in the month.
The sitings have come just ten months after Jacobs split with his wife-of-nine-years, Rosie Jacobs.
The new couple were first spotted in Bondi on New Years Day running errands and then the following day were spotted at a Bondi cafe getting smoothies.
The pair sat at a table outside the cafe with Steve dressed in a black tank top and black shorts, while Emma wore a white t-shirt paired with a grey and purple tie-dye skirt.
Later in the day, the couple were spotted shopping for homewares together in Bellevue Hill.
For the shopping trip, Steve changed into a pair of tribal printed shorts and a white t-shirt while Emma swapped out her white t-shirt for a white button-up shirt that she had tied in a knot at her waist.
It is unclear how long the couple have been together but it has been confirmed that the Channel Nine star split from his wife in March 2018.
Steve hinted in a November interview with WHO magazine that it may not have been his decision to end the marriage.
"I've been thrown a few curve balls, which were unexpected and unwanted," he revealed.
"But I suppose these things happen in life and they give you character and make you stronger and you move forward."
