The short answer is no, none were released into circulation.
In 1919, the Australian Government considered replacing the large round bronze Halfpenny and Penny with smaller and lighter coins.
The coins were intended to be normal general circulation coins rather than commemortives.
The proposed designs were all square with rounded corners and were to be made from nickel. They featured various busts of King George V on the obverse and various kookaburra designs on the reverse.
The two proposed square Halfpenny designs were 14mm in diameter and weighed 1.91 or 1.97 grams compared to the bronze Halfpenny of 25.5mm and 5.67 grams.
The eleven proposed square Penny designs were 18mm in diameter and weighed 3.79 to 4.67 grams compared to the bronze Penny of 30.8mm and 9.45 grams.
The coins are dated 1919, 1920 or 1921.
There was a limited quantity minted and they were handed around to various government officials and others for assessment, but not all were returned.
Apparently, they were not well received by those who did the assessing, and of course, they were unsuitable for slot machines.
They are quite valuable if you are fortunate enough to have one.

How many pennies in a square foot?
There are 304 pennies in a square foot 16 pennies = 12 inch line. 16 X 16 = 256 *************************************************************** Despite the difference of 48 pennies between the two answers above, both answers could be correct. If pennies were square, then answer #1 would be incorrect. Answer #2 relies on the pennies being arranged in a grid pattern. 16 x 16 = 256. However pennies are circular and can be "nested" when arranged. That means that the first row would be 16 pennies. The second row would be 15 pennies, the third row would be 16 again, then 15 again, etc. Because of the nesting, additional rows can be added in the same square foot of space. I haven't tried to see how many more pennies could be accommodated by this nesting (or "staggering") so I don't know if the 304 is an accurate count in such a case. However there would certainly be more pennies per square foot in a nested arrangement than in a grid arrangement.
