Been getting a number of calls from them. I have called Telstra Unwelcome Calls Department on 1800 805 996 and they have now blocked this number.
They said even if you are on the Do Not Call Register, it does not stop automated systems from calling. It only stops telemarketers … real people… from calling.
Hope this helps.

Missed call, called back to a voicemail from the heart research institute.

They have called me once a day for the last 2 weeks. Getting annoyed

Called Wed 29-10-2014 at 1:36pm - right in the middle of lunch - said she was Judith calling from Doctors and Helicopters - reverseaustralia has listing for this number as CareFlight. Gave her short shift.

Got a few calls from this number, got woken up sick as a dog only to be hung up on..somebody put an end to this!

Had one missed call from these people and rang them back in non business hours and the messagebank says "if you do not wish to receive anymore calls from us please enter your phone number after the tone" I did this and hopefully they will stop calling, hope this helps the rest of you :)

I got a call, rushed to phone, then they hung up. By the look of the rest of these comments, these people are probably scammers!

Received a couple of calls this week from this number. Unfortunately, if they're fundraising for a charity, they're exempt from using the Do Not Call register.

I just got a call from this number today asking for donation $ 69.99

Getting calls from them too does the Do Not Disturb register mean nothing

After reading what Sandy posted (May 2014), I called back on my phone they call on, it said it was Care Flight. They offer to let you tell them you don't want a call back. So I put my home number in and it then hung up.
Hopefully that will be the end of it!

Been ringing daily two or three times for the past couple of weeks. Hangs up as soon as I answer.

Oh, I see. I have just returned from overseas trip. they obviously got my number phoned yesterday & today but no-one speaks. I am not impressed either

calling me daily I don't know why. I now have the number on auto reject.

Care Flight rings me everyday but do not want to talk. rang on their phone number and had to take my name off their list. what a pain in the back. I was sleeping after a busy night shift in the hospital. was not impressed, had to use all the swear words I knew at the staff. felt sorry for the staff at the end but that is not an excuse to wake up someone after their night duty.

Called tonight, hung up as soon as I answered the phone. Called the number and it was Care Flight.

hung up when asked their name

I got one yesterday and when I called back on my blocked mobile number, it said it was Care Flight. They offer to let you tell them you don't want a call back. So I put my home number in and it disconnected.

Caller said they were from CareFlight and then said the call would be recorded. I hung up.

Get you`re selves a 1500 listings call blocker via ebay and solve the problem, I did.
