After making the trip abroad and landing at Concord, Gildart would look to have an immediate impact on the Tigers, making his debut in Round 1 against the Storm.
By July however, the Englishman was out the door with a loan move to the Sydney Roosters, where he would manage just a pair of appearances.
Lifting the lid on his rollercoaster first season down under, the 26-year-old detailed the mental impacts his spell with the Tigers had on his health, with Gildart left with "no family, no friends and no support."
"I played eight games at the Tigers but it didn't work out the way we planned it," Gildart told the AAP.
"That was the toughest period in my career, mentally more than anything.
"I was on the other side of the world with no family, no friends and no support really. That was pretty hard.
"I kept my head down and tried to be the best player I could ... went to the Roosters and learned a lot.
"I could have gone back to Super League (last year) but I want to give it a real good crack.
Like his move to the Tigers, the Hindley-born centre will be a key piece in the Dolphins' system as the Redcliffe-based club plan to manoeuvre through their first season in the top flight.
Gildart won't have to wait long to face the Roosters, with a Round 1 bout in Brisbane scheduled for the club's first-ever NRL tie.
A clash against the Tigers won't come for some time however, with the Dolphins' sole clash with the venture club to take place in Round 25 at CommBank Stadium.
