I suggest you contact or look up the advice from the Australian embassy - they have up to date information on tourist travel to any given destination. I am pretty sure it would not be advised and I am also sure that members of a gaming forum will not be able to give you that advice. (Except possibly Old Andy).
In this case it would be DFAT (The {Australian Government} Department for Foriegn Affairs and Trade)

We strongly advise you not to travel to Afghanistan because of the extremely dangerous security situation and the very high threat of terrorist attack.
If you are in Afghanistan, you should consider leaving. Australians who decide to remain in Afghanistan should ensure that they have personal security measures in place. You should monitor local information sources for details about the safety and security environment.
Due to the increased threat of attack expected following the Taliban's announcement it will begin a spring offensive on 1 May, Australian officials in Kabul will be taking additional security measures and limiting movement in the city in the coming days.
All major hotels in Kabul continue to be attractive targets for terrorists. Credible reporting indicates there are renewed and ongoing terrorist threats to the Serena and Intercontinental Hotels. Australians are strongly advised to continue to avoid the Serena and Intercontinental Hotels and their surrounds at this time.
Militants continue to plan and carry out attacks in major cities.
Serious terrorist incidents, including suicide bombings and other bomb attacks, occur regularly in Afghanistan, including in Kabul and Kandahar.
We continue to receive a stream of reporting indicating that terrorists are planning attacks against a range of targets, including places frequented by foreigners, airports, hotels, guesthouses, media centres, military installations and Afghan government buildings. Recent reporting suggests diplomatic premises and convoys may be particular targets. For further details see the Terrorism section below.
Due to the dangerous security situation in the provinces surrounding Kabul, you should only travel in secure transport, using reputable local drivers and guides. Australian officials use heightened security measures when travelling. You should consider dedicated armed protection, though even these precautions cannot guarantee personal safety.
There is a continuing high threat of kidnapping against Westerners, including journalists and those working for non-government organisations (NGOs) and international organisations.
Unexploded landmines and other ordnance remain a danger throughout Afghanistan.
The provision of consular services to Australians in Afghanistan may be severely restricted due to the safety and security environment. Consular assistance should be arranged through the 24-hour Consular Emergency Centre, which can be contacted on +61 2 6261 3305. See Where to Get Help for further information.
Because of the dangerous security situation, we strongly recommend that you register your travel and contact details with us so we can contact you in an emergency.
I think that sums it up. Do not go, and if you're already there get out, and get a bodyguard. You cannot expect the Embassy to help you if/when you get in trouble. As an obvious foriegner you're walking around with a target painted on your back.

As a postcript here's what they say about Afganistan's airlines:
Airline Safety
Due to safety concerns, Australian officials minimise travel on domestic and international services provided by Ariana Airlines. Australian officials also avoid international travel with Kam Air where possible. All Afghan airlines were banned from flying in EU airspace in 2010 due to safety concerns.
