The average gold price year to date is $2908 which means A$100,000.00 would have bought 34.39 ounces of gold if you bought $444 every weekday of 2023
If you bought all A$100,000.00 at once it would depend on your timing.
Example 1: Bad timing
if you bought on 31/10/2023 the gold price was $3,150.20 which would have bought 31.75 ounces. 2.64 ounces less.
DCA would have bought you 8.3% more metal
Example 2: Perfect timing
if you bought on 16/02/2023 the gold price was $2,651.00 which would have bought 37.72 ounces. 3.33 ounces more.
A single purchase perfectly timed would have bought you 9.7% more metal
Conclusion:
Unless you are able to time the market perfectly, dollar cost averaging is a preferable strategy.
