This is one of several mobile number used by a dirty rotten collection agency i.e. CPA who are ruthless and will not leave a message. all mobile numbers begin with "0451 518..."

I am getting these calls from 0451 518
Numbers twice a day driving me crazy I have blocked most of them now as they aren't leaving messages it's just silence the one message that was left.
0451 518 475
0451 518 424
0451 518 495

I got inundated with calls for over a week from this number and about 7+ similar numbers.
I answered the 1st call & got silence. So I knew it was possibly a scam/telemarketers so I ignored the rest.
They called every day, then twice a day, sometimes 4 times a day. I was getting so sick of my phone ringing while I'm trying to work.
Eventually they caught me in my car, so I didn't look at the number on hands free.
It was REAL LIFE INSURANCE asking me if I'd heard of them and trying to give me quote on life insurance.
She wouldn't take the hint when I told her I wasn't interested over 6 times. Arrrrgghh..... They called me last month about the same thing, @$%& OFF!
Numbers used: 0418 640 837, 0451 518 475, 0451 518 466, 0451 518 443, 0451 518 462 + others I didn't save.

Made contact.....it seems it is a call centre that charities use. In my case, I had just signed up to support Canteen and the various numbers beginning with 0451 518 4 were people contact me to confirm the form I had signed a week earlier. It seems they don't leave messages in case they have been given a bum steer with details

I think it is a call centre used by charities. Can't be sure as I haven't answered and no message left. I signed up to a regular donation plan for a charity last week so strongly suspect it's that company based on the previous reports here.
Have since cancelled the plan when I read the fine print that the company running it receives 88% of the donations in the first year!

Started receiving multiple calls each day from 0451 518 475 just five days after becoming starlight foundation donor at one of their shopping centre spruiking stands run by appco group support pty ltd.
Not impressed.
I've been on Do Not Call Register for years but it doesn't help in situations like this.
Just ignoring all calls from this number now.

Keep getting calls, no voicemail.

I have also cancelled due to this reason. I'm currently getting calls as well from mobile 0451 518 454 0475 440 475.

agreed to sponsor a child in a doorstep appeal the other day. Since then I have literally had 2-3 calls from this and similar numbers - I assume trying to get me to donate to other charities... It's now making me second guess my donation and consider cancelling it... But that would only disadvantage the child further.

This number called me 2 minutes after 0451 518 454. I didn't answer either call and they both rang for a short time without leaving a message.

omg i have just had 3 of these numbers plus 2 more call me now i know its them ill definately not answer im one who doesnt answer numbers i dont know if they want me leave a msg or i dont call u simple thanks for your help

Keep getting calls from 0451 518 475, 0451 518 476 and 0451 518 440. Pain in the arse. Never leave messages.

i get a call every day from this number and i have no idea who it is they do not speak
