Now the maths...
The figures you show on a per household basis had you paying interest of 17% on $96,000 = $16,320 (yes some principle would have been paid off, about $50 if first 6 months).
That figure is post-tax income that you have paid with of course and was a stunning 58% of the AWOTE figure.
Converting to the same 58% figure today would yield an interest payment amount of $45,876.36.
Dividing that by the easily available mortgage rate of 4.75% (very conservative can get below 4% easily but for argument's sake) = 45,876.36 / 0.0475 = $965,818.10 Mortgage.
See, on a like for like, you and your partner in purchase were paying the equivalent of servicing a near enough to $1m mortgage in 2016 for you $96,000 mortgage in 1989.
Using the more realistic 4.00% mortgage rate, would see a mortgage of $1,146,909
On the current lowest quoted 'bank' variable mortgage rate of 3.59% gives $1,277,893
That is a like-for-like comparison. Median mortgage not found in 30 seconds so here is the average (which over-states the size) NSW one is around $450,000 - so you were effectively servicing what would service a mortgage 2.1 to nearly 3 times the average NSW mortgage.

So do you remember how the 'experts' were predicting the possibility of even higher rates and encouraging people to lock in fixed rate debt? It was luckily before I was involved in the mortgage-go-round.
Do you remember Bob Carr encouraging people subsequently to default on their fixed rate mortgages that the State Govt of NSW had offered for people fearful of the variable rate mortgages going higher? Ending up causing many super funds to lose (in total) north of $100m. I never did buy those NSW Govt securities for the funds I ran...
Even worse than the 17% rates were the bridging loans at 22%+. Those were interesting times indeed. One of the few times that real people could participate in the high rates (if saving) through buying Treasury Notes at the weekly RBA T-Note auction (min $5,000 and awarded at lowest rate awarded in the tender). No rapacious spread taken out so you could end up with over 17% for 13 weeks (never game to go for the 26 week ones).
About the more affordable in 80s - the RBA (and I and others who have run the figures) disagree. The cost of servicing a typical mortgage (even down to 1989 Sydney median house price vs 2016 Sydney median house price level) was a greater % of median disposable household income than it is today at today's interest rate levels. See graphs posted earlier - although those are comparison of Australian median house prices vs median household disposable income.
Totally agree - if (and when) interest rates rise 2 or 3% then the 2016 ratio will rapidly approach (and potentially by-pass) the 1989/90s figure. Until then, it is currently more affordable.
Also as I posted earlier, when you look at the pre-tax case it is substantially easier in 2016 and then you should add in the near tripling of 'middle class welfare' that has happened since then such as baby bonus, family part A and B etc etc etc.
The tax free threshold has more than trebled from what it was in 1989.

and updating it for rising income, rising house prices (used 50% but that is more than Aust-wide figure is) and falling mortgage rate - has it BELOW the average for the ratio since 1980.
Sticker shock and shock-jocks/newspaper fillers and lobbyists are almost NEVER reliable sources of information. A blank sheet of paper and a calculator would save millions of Australians from poor financial decisions.
Unfortunately most implicitly (sub-consciously) have the hold-over from school days - what you see in print is correct and you believe it accordingly.
