I am sure of it. I just happened to be reading about this type of things last night. Here is what the Australian Government has to say about the issue
If you receive a scam message:
* Ignore it!
o If it sounds too good to be true – it probably is!
* Never send any money in response to a scam offer!
o No matter how convincing the offer seems.
* Once money has been advanced in response to a scam proposal, the Australian Government has no legal power to assist in its retrieval.
* The recovery of funds in these cases is a private commercial matter and the onus is on individuals to recover their losses
o The Government can assist only by providing the names of in-country legal representatives.
* Travel to the country concerned to retrieve any money that may have been advanced can be very dangerous and should be undertaken with extreme caution
Since 1992 at least 17 people have been killed in Nigeria alone attempting to recover their funds.
Convinced? or want to read more?
