After I logged in https://itunesconnect.apple.com successfully, there's not any element shown on the web page (A blank webpage).
I used Chrome, Firefox, and Safari, but the same situation occurred. And this situation lasts almost 1 week from Australia, not only from Sydney, but also from Melbourne.
Works fine for me in QLD.
I've also been experiencing this issue in QLD. Nothing but a blank screen with a faint grey horizontal line in it for 4 or 5 days.
Same. I'm in Qld too. I first noticed on Friday morning I had no access. Submitted a support request, and was later told the issue was resolved. On informing them it still didn't work for me, I was told that it most definitely was resolved, and it was probably a cacheing thing, and to clear my browser cache and try again, or with a private browser window. Tried this. On multiple computers. Nothing worked. They also told me it should "resolve itself" in the next day (this was Saturday morning). It's now nearly 1:30am Tuesday morning and it still doesn't work for me. I hope they have this fixed soon! (And I hope they realise that saying it's fixed when it clearly isn't doesn't actually help very much).
This is a big problem for many Devs throughout much of the world. There are quite a few other threads here on the subject.
One workaround is to use a VPN for the UK or Germany (two of the few places for which iTC still works)
Or you can try the workaround given by Matthew Lenton on his Twitter Feed:

I'm sure he's tried to post his workaround here, but he probably included links to the before and after pics in his post, which would have sent it into moderation (a state of limbo that can last many days).
It's been confirmed as working on 9to5mac.com (It has it's own article). The pictures are a little hard to read due to being low res, but basically:
