How to establish secured tunnel between two private IP hosts via Internet?

One of the secured server we have in our Melbourne lab need to be accessed from our Singapore location. We tried to engage the IT guys to enable the connectivity but they have informed us it can't be done. Well, With the current infrastructure, it would incur very high latency and it wouldn't be useful for us because of the the same.

The approximate latency he have mentioned is 10Seconds!

This actually got me into exploring alternatives on our own. Can someone guide me whether it is doable with two Private IPs? If not, I will have to get atleast a public IP at one end point.
