Based on the provided information, it appears that the caller with the number +61451359288 made a call to the user, but the purpose of the call is unclear. The user mentions that the caller started talking and then stopped without leaving a message, making it difficult to determine the intent of the call. The fact that the caller did not leave a message suggests that it may have been a mistake, a telemarketing call, or a scam attempt. However, without more information, it is impossible to say for sure. The user's inability to make out what was being said adds to the uncertainty surrounding the call.
