I keep getting fake emails from onlinetravel @ webjet . com . au - how do I block them as the MS outlook blocked doesn't work

You cannot block fake/spam emails from being sent to your email address. All you can do is filter them after they get there. You should be able to use your Outlook filter options to create a filter to move emails from that email address to your spam/junk folder or the trash folder.
