Former Wakefield head coach Brian Smith says costs were "cut to the bone" at Belle Vue, forcing his resignation from the Yorkshire club.
Smith, 61, left the Wildcats just five games into the new Super League season, citing a lack of funding as a main reason for his departure.
Wakefield chairman Michael Carter says he was stunned by the Australian's exit, but admitted the pair had suffered a "frosty" relationship since Christmas.
Smith, who had been in charge for just nine months, explained his decision to supporters via a message on Facebook.
"For those who want to know, I am on my way home to Oz," said the Australian, who went on to warn Wakefield fans about the future of their club.
"My own health, my family and those two lovely grandkids matter most to me.
"Others may not understand but heading the coaching part of a footy club where costs are cut to the bone takes a huge commitment and loads of energy.
"All coaches at every level count on support of all kinds to get the job done. That's when it's really fun and amazing things can happen - it happened at Hull FC and wow it happened at Bradford Bulls too.
"Lots of people said very nice things about me then but the truth was it was the belief and commitment of the whole place that led to great successes.
"You people who love WTW (Wakefield Trinity Wildcats) or are just footy lovers need to react before it's too late for a great old club. Yes I believe it's that serious."
Carter had previously stated that Wakefield had the highest playing budget in the club's history during Smith's tenure.
Smith's younger brother, Warrington coach Tony Smith, says he understands the reasoning behind his sibling's sudden departure from English rugby.
"It took me by surprise but at the same time, knowing a little bit about things, I was not surprised," said the former Leeds and England boss.
"I know my brother is experienced enough and wise enough to know when things aren't right.
"If things are frosty to the point where communication isn't coming between two senior people within a club, it's not a great recipe for success and I think he recognised that and took action.
"I think they've improved enormously from where they were last year. The fact that he felt things aren't improving enough in enough areas probably says a whole lot, because wherever he's gone he's been able to turn teams around and leave them in a better state."
