Why are there people saying that "I am using WGS84(ITRF96)"?

There are newer version of ITRF. Will WGS84 follow it?

If so, what will be the influence to us?

Hey I think this is your answer to the question:

Dont know if it really helps but it does state what each is and that WGS is regularly aligned to ITRF.

Basically as you know, two types of Co-ordinate reference system.

or this is better as it is not purely Oz based. gps.gov/multimedia/presentations/2009/09/ICG/wiley.pdf –  Gerald Jan 18 '13 at 11:33
    
Still, I doubt how different ITRF can be used at the same time. –  Harold Chan Jan 18 '13 at 12:00
    
you can set up a custom CRS using the official (+towgs84) parameters published by ITRF: itrf.ensg.ign.fr/ITRF_solutions/2008/tp_08-05.php. Dutch Marine Office has issued a Windows Porgram called PCtrans to do such calculations. –  Andre Joost Jan 18 '13 at 12:23
    
As far as i can see you should not be using several different versions at once only one for the project. As Andre says, set a custom CRS which will allow something with a CRS of lets say WGS84 be transfromed so it displays correctly on OSGB64. I was just about to post the same link as he has done to show alterations. –  Gerald Jan 18 '13 at 12:26
