A couple of years ago I wrote a small Windows app to produce any size grid,
albeit only for British National Grid - the output is a single .mif file
containing the five E + N references for each grid, this is then easily and
quickly imported into MapInfo.

By way of comparison I created a 250m grid for the whole of London in
MapInfo's Gridmaker, this took around 90 minutes to produce ( at the time on
a 486 ), the utility I wrote in 'c' took around 7 minutes.  That is down to
about 40 seconds now on a 233!

I am not familiar with your co-ordinate system but I image, being Australia,
it is similar.  I would be willing to have a look at the source code to see
if it could be modified without burning too much midnight oil.

Perhaps you will let me know, certainly you are welcome to try the existing
application if you wish.
