Trek to the camp starts from Pokhra which is another famous touristy destination in Nepal other than Kathmandu. If you are planning to visit Nepal then you just cannot afford to skip Pokhra.
You can start hiking from Kande or Phedi but to reach there you can either hire a cab from Pokhra costing around 5000 bucks or use public transport which is definitely way cheaper. If you opt for public transport, you would need to change the vehicle thrice but trust me its worth it. You would not only save quite some bucks but also get a chance to travel with locals and get an idea about life at this place while witnessing miraculous beauty of nature.
If you are staying at lakeside in Pokhra get a local bus to Prithvi Chawk. It takes 20 minutes to reach and costs 20-30 NPR. Get into another bus/auto to Hari Chawk. It would take another 20 minutes and around 30-40 NPR. Now take another bus from Hari Chawk to Kande. Frequency is every 15 minutes and would cost somewhere around 80 NPR. Bus will take almost an hour to reach Kande while offering stunning views of snow laden mountain ranges. That's how we reached.
After getting off the bus we could see boards indicating way to Australian base camp. Post having some refreshments and taking water bottles we began hike from Kande. Trail was a bit steep but had proper stone staircase so worry not if you are not a trekker. Its pretty safe and ideal for any age group. Nature was amazingly beautiful en-route. Sparkling snow clad mountains with refreshing greenery and cool breeze helped us to replenish. Mere thought of hiking in Nepal, the trekkers paradise raised our adrenaline levels. .
