The girlfriend of a tradesman who was electrocuted on the job has revealed the heartbreaking moment she realised her boyfriend was planning to propose.

Jaime-Lee Digby's partner Luke Bray, 24, was electrocuted while working in the roof of a home in Carlton, in Sydney's south, in February.

Ms Digby spoke about the horrific ordeal and their whirlwind romance when she fronted the media on Wednesday.

'Luke and I met on the Navy, we were on the same ship together. Things went very, very quickly,' she said.

'When this happened it tore my entire life apart. I lived here all by myself at the time, so I had to fly my parents down from the Sunny Coast to go and identify his body.

'I then had to collect his belongings from the police station, which had a receipt for an engagement ring...it's been very, very painful.'

Following Mr Bray's death in February, Ms Digby shared the heartbreaking story of the engagement ring on her Instagram page.

'When it came time to identify his body and collect his belongings I was made aware of something incredibly special inside his wallet,' she wrote.

'In his wallet was a receipt for a beautiful cushion cut Halo engagement ring from Armans Jewellery.'

Ms Digby entered a competition posted by Armans Jewellery in the hope of winning a ring.

'We had always spoken about the day that we were to meet each other at the aisle and I would like nothing more than to fulfill his dream,' she wrote.

'Winning this competition would complete me and our aspirations of becoming engaged as he was so desperate and worked so hard to make it happen.'

Reports indicate Mr Bray was killed by power flowing into the house through illegal wiring, despite power being switched off at the mains.

There were desperate attempts to save the former Navy sailor but paramedics were unable to revive him.

'No person should go to work one day and not make it home alive by the evening,' Ms Digby said on Wednesday.
