SBS Correspondent Vic Caruso is at the scene of the rescue effort and said rescuers have so far drilled about 5.5 metres towards the miners, and have another 10.5 metres to go until they reach the men.
He also reported that while authorities have had no problems with the drilling itself, the toughness of the rock has meant the process has taken longer than anticipated.
Mr Caruso said rescuers are hoping to hit a soft-spot in the rock that would further speed up the process.
Mine manager Matthew Gill has refused to speculate on how much longer it will take to free the two men, but it is widely believed that it could be on Saturday.
Todd Russell and Brant Webb have been trapped in a steel cage almost a kilometre underground after a rock fall on April 25 at the Beaconsfield Gold Mine in northern Tasmania.
A third man, Larry Knight was killed during the accident.
Families of the miners had visited site to discuss to the rescue effort.
Hot food
The men have been passed containers of home-made chicken soup, pushed through a 90mm PVC pipe with a pole, the first warm food the men have had since tuesday last week.
Parademics who have spoken to the miners have described them as chirpy, chatty and cheeky.
But they have also experienced low moments in which they just want to get out.
"As I've said previously, what we are doing is unique. It's unfair to set deadlines and then get expectations up that we then miss. These guys know we are doing everything possible," said Mr Gill.
He said despite the delays in bringing the men to the surface, the pair had been able to sleep overnight and are in good spirits.
Musician sends message
Rock star Dave Grohl of the Foo Fighters sent his best wishes to the men, after one of them requested the band's music be downloaded onto iPods sent down to them to help them pass the time.
Mr Gill said the pair were "stoked" at the message, and are concerned about how their families are coping.
The men even joked with their boss about their conditions, including the fact that one had resigned from his job from 925 metres below the surface.
"He wanted to know if I'd heard (about the resignation). He said it was verbal and I said, 'Well, I wanted to talk to him about that. So I haven't accepted his resignation," Mr Gill said.
"We didn't talk overtime but I did talk to Brant about lying down on the job. I explained that I had seen him sleeping on the job. I explained that I must have gone soft because it's the fist time in my years in the industry that I've seen an employee sleeping on the job and left them to sleep on the job."
Mr Gill said one of the things he asked them was: "Is there anything you want
to say or have a go at me?" but they declined.
"They just said 'Do it safely'. They weren't concerned at the time at all.
"They were appreciative of the support they are getting... They were really appreciative of that, almost apologetic."
