Airlines/ Airports

I had bitter experience with Australian Customs at Melbourne Airport.I went to visit my son in Melbourne australia even after giving delcalration some Indian sealed packet of Garam masla/Dhansak masala/ spices that I was carrying was taken out by customs and thrown in quartine bin saying it had cotain of clove which is prohibited.no where in theri rules and regulation it was mentioned, I could not cook Parsi dish dhansak which my son likes the most and not tasted for years(4-5years).
2.while returning from Melbourne on 6th 0015hours flight MH128 all my 2 Perfume 200ml bottles, shower gel gift box and shampoos, conditioners were taken away, I requested them to send by cargo they refused to do saying small items can not be send in transit flights so nor they refund me the amount of $200-300,that I spent my hard earned money on that/ I got gift from my son. This is very heart broken for a mother for an common men to have such great loss.
 This is not done.
I had first time travel to Australia and have this bitter heart broken experience.
On my Malaysian Airlines tickets no.2321:477:696:6 place of Issue Pune India. It is clearly mentioned that “Medicine and toiletries in limited quantities which are necessary or appropriate for the passenger during journey such as hairspray, perfume bottles, and medicines containing alcohol may be carried. Many of these listed articles can be carried as air cargo provided they are packed in accordance with cargo regulation.
When these items are prohibited to take in flight how come These Flight/Malaysian airlines etc sell perfumes, cigarettes, huge Alcohol bottles at airport Duty free shop people carry with them because it is sealed by duty free shop that do not mean it do not have prohibited items.
