Keeping in mind that time is quite limited, so you have to stick pretty close to home (although not necessarily right IN your town - just anyplace you could go as a day trip), try looking around you with the eyes of someone who has never seen your area and tell us some things you'd share with...A Visitor to Your Hometown
Firstly, she would just HAVE to stay for two days, because Australia is so spread out.
1. Your visitor wants to see something historical. Where would you take her and why?
Ballarat’s Sovereign Hill (1/2 drive from where I live) because it’s an outdoor museum replicating the hustle and bustle of the 1850s. You can pan for gold or visit the blacksmith shop, candle maker or other shops there. Mind you, you need to watch out for the horse-drawn vehicles. After that, whilst not historical, I would take my visitors to the Ballarat Wildlife and Reptile Park to experience numerous Aussie creatures, come in close contact with koalas, emus and other native animals. For lunch, there are many scrumptious places to choose from. In the afternoon I would suggest we visit an art gallery to view the original Eureka Flag and Australian art.
2. She wants to see something hysterical...well, mildly amusing anyway. She'd even go for cute, quirky, odd, or unique. Where would you take her and why?
We would hop along to a Circus Oz show. The performers presents audiences with a circus that is also a playful theatrical subversion of the idea of 'circus'. Not your average circus.
3. She wants to take some beautiful and/or interesting photos to fill her albums when she gets home. Where would you take her?
We would take a day drive along the Great Ocean Road, a breath-taking drive along the South-West Coast of Victoria. We would stop to look at the beach, waterfalls and parks. We would stop at coastal towns including Torquay, Warrnambool, and the historical villages of Queenscliff and Port Fairy.

I would not recommend buying something but rather finding a seashell, some driftwood and maybe seaglass from one of the many beaches we would visit. However I would suggest taking only one shell, we must leave shells for others to enjoy.
5. Wow, it's been a long day and you're both ready for a snack, or maybe even a meal. Where would you take her to really get the flavor of your area?
There are many wineries to visit, and I would recommend Witchmount Estate to sample some local wine and Italian menu.
