Australia were already in a great spot to win the match. That's generally how it is with declarations.I understand your point. But at the moment, the game is fully live. If we'd batted on, I'm not sure that would have been the case. You could argue that we could have batted on to 500 or 600 or 700, but as it stands, we're in a good spot to win this match, but very unlikely to lose it. So, yeh...
How would another 15 overs of batting have had any bearing on Sri Lanka's batting performance? If Australia had tried to up the rate they'd typically be a further 50+ runs ahead right now, all things being the same. Could also have had the option to enforce the follow-on, although I suspect Clarke wouldn't anyway as he's incredibly averse to using it.
