He leaves behind his 29-year-old wife Ashleigh, who is expecting three babies later this year.
Cricket coach Matt Conwell, 32, died on September 2 in what police say was a suicide.
Ashleigh Conwell, 29, has been left heartbroken and pregnant after the death of husband Matt who family says had been struggling with his mental health during the pandemic
“It was a snap decision, a moment of clouded judgement, and totally out of character,” she told the Courier Mail.
A woman pregnant with triplets has been widowed after her husband took his own life during Australia’s coronavirus lockdown.
“This year’s been tough for everyone, even the strongest people you thought could get through it, and while there were some struggles and stresses there, it just shows suicide doesn’t discriminate.
Her sister Emily said her brother-in-law had been struggling with his mental health as a result of the pandemic.
A GoFundMe page set up for the grieving mother-to-be has received more than £143,000 (£79,000).
“The outpouring of support is a testament to the kind of person Matt was – very non-judgemental, very genuine and caring, an unassuming, quiet person who had time for everyone.”
“Not only has Ashleigh’s world been torn apart emotionally, the financial hardship she now finds herself in is significant.
“This has now been made so much more difficult for Ashleigh with the loss of her beloved soulmate, who was so looking forward to meeting his babies.
“The pregnancy, delivery and care of triplets is challenging for any couple,” it reads.
“Both Matt and Ashleigh had been impacted by Covid-19 in their job roles; they were already stretching every dollar and budgeting tightly for the arrival of their unexpected but so very wanted ‘instant’ family.
“Losing Matt has placed an almost overwhelming burden on Ashleigh.”
But cricket was his main passion, and there has been an outpouring of grief from many Queensland-based cricket clubs.
Mr Conwell, who was also known as “Cozzy”, worked with professional and premier grade sporting clubs, including as a strength and conditioning coach for the Brisbane Roar Football Club.
“Matt always presented a smiling face and he will be sadly missed by everyone who had the privilege of knowing him,” WPC Cricket Club President Peter Davies wrote on the Wolston Park Centenary Cricket club’s Facebook page.
