One new Married at First Sight Australia couple has difficult start as bride's limo breaks down before wedding

And despite attempts to get the car back up and running, it appears that it's going to be a struggle for Tamara to get to the wedding on time.

The incident only adds to the pressure on Tamara, who says: "Now I'm really nervous, because I'm late and the car's not working and I'm about to marry a stranger!"

She adds: "It's important for me to make a good first impression, but now that's ruined."

Tonight's episode is shaping up to be a big one, with the experts set to introduce two new couples halfway through the experiment for the first time in the show's history.

The first of those couples is the aforementioned Tamara and Dan, who the experts hope will be a good match due to their strong family values.

Tamara, whose mother passed away three years ago, is described as "an optimistic brunette", while Dan is introduced as "a down-to-earth Aussie bloke with a young son."

Meanwhile, the other new pairing sees no-nonsense 25-year-old single mother Susie tie the knot with "empathetic" 28-year-old Billy, who was himself raised by a single mother.
