The Antarctic vortex / super low weather system has certainly got folks in Melbourne huddling indoors.
An outdoor team building solution may not actually go down that well for team morale in such weather (unless of course you are literally running a military officer selection course where such hardships are warranted).
If however you have a normal conference group or business team seeking some fun, interaction and possibly also serious learning outcomes then an indoor team building approach (like the When in Rome business game pictured here) is likley to get far better results, and appreciation from your people.
Team Building is often misunderstood as a largely outdoor pursuit when in fact many of the best solutions are actually indoor activities and business games.
Many styles of approach such as painting based team challenges, film making or even great table top business games exist to challenge and engage people in relative comfort and safety away from the biting cold that a typical winter's day in melbourne can produce.
Team Building Melbourne does not need to have people running about outdoors and suffering without need when there are just so many great indoor team building options to deploy these days.
