Unless you copyright your work in Australia, other people can easily steal it and pretend it's theirs.

I have lived in Germany and Norway. Patent protection and intellectual property (IP) is very relevant and there are strong patent and trade laws, but "pirating" digital content is commonplace. However I think that IP protection is going in the wrong direction. The value of an artist or work of art is in the act of its creation. Not in selling as many copies as possible of this work. Therefore, I think we should encourage models that pay artists for creating art, not selling it. For example, culture funding and crowdfunding models pay artists to create new works, not sell old ones. Also, if a work of art is "free", after that it has been created, others can improve on it. This is very important to foster creativity in music, literature and also graphic arts. There has even formed a political movement in Europe that tries (among other things) to liberate digital works and abolish patent protection. The "Pirate Parties" were first founded in Sweden, but have spread all over Europe. In Germany, they already reach 10% approval, and have obtained seats in regional parliaments.

Yeah, here in pakistan this is normal routine work. Here laws exist but nobody is obeying these rules because if they follow it. They have to pay for it a lot of money that is not easy for every person. Thanks
