I wish you luck.

If you rely on the standard formula for converting Northing and Easting
on the Oz grid to latitude and longitude, buckley's. With latitude and
longitude, I have passed addresses to Google and had (some would call)
fairly close results come back; when I did a reverse lookup (on Google)
using the data provided by Google, the result was always within 150
metres. If I converted northings and eastings to latitude and longitude,
well, some results weren't even in the right suburb. I relied on the
northings and eastings provided by UBD. Where did yours come from?
Surveyors? How accurate was the survey? Was it perhaps close to
lunchtime? Or 4:45PM?
I once had some land on the edge of a state forest re-surveyed by the
licensed shire surveyor because there were falling-down 100yo fences
everywhere. Does "Five acres or thereabouts" sound accurate to you?

Oh, quite high, I'd say. That is, given my experience driving on
back_country roads in NSW.

You can download a replication tool from SQL Maestro (or Navicat) and
use the Paradox ODBC driver (the one that came with Paradox) to just
replicate the portions of the database you want into Paradox tables (and
vice versa). I think there's a 30 day trial on it so it should do what
you want within the time limit.
