Firstly, I like the rule that you never take off from an airport you can't land on again. Unless you are flying RPT (and a whole lot more current than most of us), then the real take-off minima is the approach minima for that airport. Australia has relatively simple weather patterns, most of the time a 2 hour wait will yield an improvement - or a hole or a raised area of the cloud base. If we're not flying RPT its rare that we can't deal with the delay.
Secondly, once you're at the minima, the missed approach procedure may be a useful guide.
Most of the time (one hopes) the take-offs near minima are at an airfield that you are familiar with, so you can kind of replicate a VFR climb out. If its not an airport you are familiar with, then there is probably a good argument to add some safety factor to the take-off minima and spending some time thinking about it beforehand. You may also want to circle above the field so you climb out accurately on the aid to aid track, rather than converging onto the track from the runway.
Single pilot IFR has a high accident rate and take off is a high workload environment. Unless you are doing it everyday, its worth adding margin to the minima.
So, for the test, I think the answer is, depending on the airport location (ie if its Woomera, who cares?) and your local knowledge, you climb out converging onto track, follow a missed approach, follow a SID, or circle to the circling minima then continue the climb on track.
