Hawkins told the BBC he's not angry about the slow response from organisers and spectators to his collapse but he is annoyed at himself for not preparing his body to cope with the hot conditions.
"I was in Australia for five weeks to get used to the conditions and it had gone really well.
"Even up to the point I collapsed, there was no sign that it was going to happen. I was feeling pretty normal for a marathon at 39km in.
"There was no point when I thought 'I'm over heating, I need to slow down' or anything like that."
On the other hand, Shelley is from the Gold Coast and knows the conditions better than any, but he too was suffering. He came over the rise of the bridge and saw Hawkins flat on the bitumen.
"I thought, 'oh shit he might be in a bit of trouble'," he said.
Shelley was suddenly in the lead but like Hawkins, his focus was now just on getting to the end.
"I thought 'hopefully I can get to the finish line' because I felt a few cramps earlier than expected. I tried to run my own race, I got the sponges every two kilometres and took in drinks wherever I could."
Shelley tried to accelerate in the straight to the finish but he had nothing left. He made it to the line in two hours 16 minutes 46 seconds and fell emotionally into the arms of his famous coach, Dick Telford.
Waiting at the line were Australia's three women marathon runners. Lisa Weightman had won silver, Jess Trengove bronze. Virginia Moloney finished 16th.
