In most countries, yes.
Depends if the currency it was drawn in is still legal tender. If the currency no longer exists then you won't be able to cash it.
Yes all Scottish notes are legal tender throughout the UK, that is in England, Northern Ireland and Wales. Actually no. Scottish and Northern Irish notes may be used in any part of the UK and as they are marked Sterling, most shops will accept them. They are not legal tender however. Legal tender is a misunderstood term and does not refer to whether money is currency that can be used. Scottish and Northern Irish sterling notes are not legal tender in any part of the UK. No banknote is legal tender in Scotland or N. Ireland in fact! This money is issued by retail banks and is classed as a promissory note not Legal Tender. The expression Legal Tender is to do with debt payment laws and refers to a form of payment that is legally always acceptable. In England and Wales the only legal tender is money issued by the Bank of England and no note is Legal Tender in Scotland or Northern Ireland including their own notes. There is quite a good discussion of this on the Royal Mint banknote site.
There is no documented evidence that anybody has found an Australian Five Dollar note without the signatures. Assuming that your Five Dollar note is a legitimate Australian Legal Tender banknote and it also includes the Legal Tender declaration and a serial number, it would be very rare. Any such banknote should not have got past the quality control at Note Printing Australia.
"Can Legal Tender be refused as payment to settle a debt?", the short answer is no, but there are a lot of "buts" and "what ifs" with Legal Tender and it varies from country to country. As far as Great Britain is concerned, any demonetised coin or banknote such as the One Pound note or the Half New Penny, etc. are no longer Legal Tender. 1 and 2 Penny coins are Legal Tender in amounts up to 20 Pence. 5 and 10 Pence coins are Legal Tender in amounts up to Five Pounds. 20 and 50 Pence coins are Legal Tender in amounts up to Ten Pounds. One, Two and Five Pound coins are Legal Tender up to any amount, as are banknotes. The currencies of Scotland and Northern Ireland are not Legal Tender in England and Wales (and vice-versa), but are accepted on the basis of them being a Promissory Note by mutual agreement between the banks concerned. A shopkeeper is entitled to refuse payment if the coins or banknotes are mangled, mutilated or torn or, he cannot make change for a small purchase from a large banknote. An unacceptable coin is one where the main design features cannot be seen clearly for any reason. An unacceptable banknote is one that may have been torn in half or been washed and the colours and design are no longer visible or the paper is pulped.

All earlier Australian decimal banknotes remain legal tender in Australia even though they are no longer in circulation. You may have problems getting a shopkeeper of tradesman to accept an old banknote though. The Reserve Bank of Australia advises that old Australian banknotes can be presented at the Reserve Bank of Australia and most banks and exchanged for an equivalent value current Australian banknote.
Legal tender is everyday money.

LEGAL TENDER MONEY: A legal medium of payment.
It is a declaration informing you where the banknote will be accepted as Legal Tender or, where you can use the note to settle a debt. In the case of an Australian banknote, it can legally be accepted anywhere in Australia and its Territories, and not be refused. If you were to use the currency of another country to make a purchase or settle a debt in Australia, the person owed the money has every right to refuse any payment made in non-Australian currency. The banknotes of most countries will carry a similar declaration in respect of their own currencies and countries/territories.
it is not legal tender
