In the images, which were taken in Riverstone, Sydney on August 5, Dan can be seen surrounded by crew as he films scenes with Ethan Browne, Rob Kipa-William and Patrick O'Connor.
Claded in a leather jacket, black shirt and pants, Dan appeared to slip seamlessly back into his bad boy persona for the role.
The scenes will reportedly air later this year.
Previously, a photo posted to a fan-made Instagram account @homeandaway2020_ showed the 35-year-old actor posing alongside current Home and Away stars Ethan Browne and Rob Kipa-William, kicking off the rumours.
Dan’s character Heath was part of the original River Boys, which also included his brother Daryl “Brax” Braxton (Stephen Peacocke) and Casey (Lincoln Younes).
Though the three OGs have long since departed, Dean (Patrick O’Connor) is part of the River Boys gang, while cop Colby (Tim Franklin) previously had ties.
Willow (Sarah Roberts) and newcomer Amber (Maddy Jevic) are also River Girls.
While nothing official has yet been confirmed, Home and Away fans have claimed Heath and his half-brother Kyle Braxton (Nic Westaway) will reappear in an attempt to break Colby out of jail in a future episode.
Dan has previously admitted he’d be open to the idea of reprising his role.
"I would definitely consider it, as long as there is a good storyline," he told TV Week in 2018.
In 2014, Heath departed Summer Bay to start a new life with his wife, Bianca.
However, he has returned several times over the years, including for two spin-off specials, Home and Away: An Eye for an Eye and Home And Away: All or Nothing on now-defunct streaming service Presto.
