Text saying "We have tried to reach you! You are the WINNER of the Harvey Norman SUMMER PRIZE DRAW. GET IT NOW:" with a link.
Given I do not shop at Harvey Norman I am pretty sure this is a scam.

This number text me to say I had paid a large deposit on a computer and to phone another number in the body of text if it wasn’t me. Sounds like a scam

Text message to my mobile - Uses my first name and says "PAYOUT is ready for be addressed in your name.... Click the link and start the process - not likely!!!!

Nope

This group sends a text impersonating your bank. They obviously want you to text back or call the number providing to get your bank details.

This group of horrible people are now sending out text messages impersonating your bank, saying a payment has gone through and if this is not correct, call this number. Obviously they are hoping you will call or text back and give bank details.
