The grieving sister of a young doctor allegedly stabbed to death by two teens has called for harsher penalties after a 17-year-old accused of being behind the wheel of a fatal crash breached his bail conditions. 

Dr Ash Gordon, 33, died in the early hours of January 13 after his Doncaster home in Melbourne's east was allegedly broken into.

He was allegedly killed by two 16-year-olds, one of whom was on bail at the time, in a burglary gone wrong.

Dr Gordon's sister Natalie has now called for harsher penalties for teenage offenders in the wake of another tragic death involving a 17-year-old driver in Melbourne last week.

The teenager is accused of being behind the wheel of an allegedly stolen Jeep Cherokee which collided with a Toyota Corolla being driven by trainee doctor William Taylor, 28, at an intersection in Burwood in the city's inner-east.

Mr Taylor, who had been returning from football training, died at the scene.

The 17-year-old was charged with culpable driving causing death, dangerous driving causing death, fail to stop and render assistance, theft of motor vehicle and unlicensed driving.

But he allegedly breached his bail conditions just two days after they were handed down by failing to check in with police. He's now back in custody.

Ms Gordon said that she  'wasn't surprised at all' by the alleged bail breaches.

'Unfortunately they are reoffending more times than not, so why do we keep letting them back out into society?' she told A Current Affair on Wednesday night.

Ms Gordon has launched a petition calling for a crackdown on young offenders.

'The wider community is absolutely so fed up with the constant reoccurrence of these same issues,' she said.

'These youth are continuously stealing cars, breaking into homes and generally just scaring the community.

'So more often than not, people are wanting to sign more times than once.'

The grieving sister said she believes the government should change laws to make it 'harder to grant bail and easier to keep them in'.

'I truly believe we need to bring in harsher penalties for lesser crimes so we're stopping them from getting to this point in their lives,' Ms Gordon said.

'We really need to reeducate people on how to appropriately discipline children so that they're learning from a young age that you can't treat people like this.

'Things like ankle monitoring systems - that is only going to work for a young person who has a conscience and unfortunately by the time they're at this stage, they're too far gone.'

Ms Gordon said the emergency service workers she dealt with in the wake of her brother's death were equally frustrated.

'You can see the pain in their faces when they're having to tell families like mine the likelihood of how the proceedings will go,' Ms Gordon said.

'The police, the detectives, frontline workers, they put their lives on the line every single day ... they're always the ones copping the flak, but unfortunately they are just as frustrated as the general community.'

Ms Gordon said she hoped to make a change in honour of her late brother.

'He always wanted to make a change and he always wanted to treat people in the best way possible, hence why he went down the line of medicine,' she said.

'I purely do it for his memory and to keep his memory alive. His death wasn't in vain.'

She added: 'I never want another family to feel this pain but unfortunately there is another family starting to go through this process and I feel so deeply for them. 

'I wish that they never had to go through this. I wouldn't wish upon anybody.'
