Regex help needed

I am trying to put together a couple of regex formats for a client’s WordPress plugin form, so I am wondering if someone could please help me with the formatting of a full name (like Chris Smith) and an Australian phone number (like 0738395123)? Thanks in advance.

Ok, I have worked that out, now I need help with an Australian date and time. The Australian date and time should be dd/mm/yyyy hh:mm am/pm - the user needs to be able to enter that into the same text box. Please help, anyone.
