My naive youth would hardly have noticed the difference then.
Yep, I only realised after 2005/2006 when I became a bit of a kit nerd and would draw in class to cure boredom and stop being fidgety in class so drew a big Socceroos History pack.
The other turbulent era would be that 2004/2005 period when first changing to Nike, where we essentially rotated through 5 kits (2 home, 2 away, and 1 temporary).

First we wore this temporary navy kit - which was just a template (and very reminiscent of Nerds FC) against South Africa in a friendly in 2004. This was just days/weeks after the change to Nike was announced, so nothing was ready.
Following that, and in time for the Olympics, these became the home and away jerseys - with Green still the home colour
Before the final friendly of 2004 against Norway, a decision was made to swap to gold for home, and green away, so this was introduced temporarily:

In early 2005, we had some friendlies with South Africa (February), and hosted Iraq and Indonesia in March. With some tweaks made later on to what we all love and know, with an away kit introduced in a deeper green than the original Nike home shirt. These were definitely in place for the Iraq/Indonesia matches, but not 100% on the South Africa match.
Just found a wonderful website (which I knew existed, but didn’t know about these illustrations, which must be something new.

If only DHGATE made Aussie retros too.
There is some available at this website -
https://www.u8au.com/product-page/clearance-football-jersey - they aren’t perfect recreations, but they did the job for me.
At points They have had recreations of 1993 home and away, 1994 home, 1996 olyroos, 1998 home, and 2002 home (also 2002 New Zealand)





The two holy grails for me that I’ve been looking forever for actual versions of are the 2005 home (the final Total 90), and personally either of the 1997 ones
