for one thing, as a starter, the change over between political parties often results in good policies being trashed and dud ones replacing them in line with partisan ideology.
the swing from right to left is intensely destabilising.
voting in parliament where 2 ideologies compete and all other considerations cast aside means that diabolical deals must be negotiated, regardless of the pros/cons of the bill involved, that enables dodgy dreams to dominate parliament.
lastly it leaves parliament in a squabble fest that achieves nothing other than shaming the Aus parliament as a mob of squabbling chooks.
if this doesn't address your claim that parliament is "well functioning" you have those hallucinogenic fog lenses tuned into realising wishful thinking.
a house full of independents will need to alter the management of govt. perhaps we'll have people who actually know about such management in charge instead of career party climbers who know nothing of sensible business management. this is BOTH sides treefer. for evidence just look at what Taylor did to Snowy2, and now how the other side are crewing it all up just as badly as the LNP did.
