Two-party politics promotes gridlock. Multi-party systems, as long as they don't have veto players, don't have as much stagnation and do a better job of citizen representation.
Do they? 79% of Australians and 73% of Germans have an unfavorable view of Israel, in Germany's case 49% of all being "very" unfavorable [0]. Don't see much representation of that in their politics. Both very much multi-party systems. Australia's system in particular has aspects that are often held up as one of the best in the world. Even on important other topics, it doesn't seem to reflect things much.
Another example, if you survey basically any multi-party European state such as Germany, Belgium, the Netherlands, Denmark and so on purely on economic policies, you'll overwhelmingly find people supporting much more progressive taxation and in general more socialist economic policies. I'm talking large majorities. Including nationalization of many institutions and so on. Yet their governments have done the direct opposite for decades. Not very representative.
The better representation you're talking about is very surface level, for everything that matters the outcome is that favored by big capital.
I fear you might be mostly right about global political outcomes favored by big capital. However, both example countries you cited have much stronger social safety nets than the United States. The research shows there is a spectrum, but that multi-party systems generally do create greater citizen representation.
Martin Gilens and Benjamin page published an article that uses data to come to this conclusion about the public's influence on American policy:
"The central point that emerges from our research is that economic elites and organized groups representing business interests have substantial independent impacts on U.S. government policy, while mass-based interest groups and average citizens have little or no independent influence."
Iskander De Bruycker and Marcel Hanegraaff authored a recent study, focusing on the EU, in which they "demonstrate that interest groups with more economic resources are generally more influential, but only if their policy positions are congruent with a public majority." Sorry this one is paywalled. Such is the state of academic publishing. :(
