Should the government add or increase tariffs on products imported into the country?

not as a blanket, but specifically to help domestic industry. and the needs of domestic industry should be determined through a board of industry and union representatives to ensure both business owners and their employees have an equal say

Yes, but only where it's clear the products are cheaper due to lower welfare and human rights situations in the country of origin.
I'd prefer to see a 'Humanitarian tariff' applied such that it enabled production and sale locally at minimal cost, encouraging both sides to lift their game, capital investment, people investment, innovation etc.
So T-shirts from Bangladesh are cheap because labour there is basically slave labour, so low paid it's ridiculous.
The intermediaries are reaping all the profits. Like runners made in Indonesia, same situation. Might add 25% to…  Read more the cost of items sold here, but enable production here.
Same with cars. Buttons Plan was good, If you want to sell here, 10% must be made here or supplied from here, and not marketing or advertising. Actual components. So iron ore for the steel, bauxite or ally for the ally parts, lithium for batteries mined here...we need 'quid pro quos' to encourage manufacturing back to this country, and countries that are able to produce items cheaper than we can due to unfair advantages (taking advantage of workers for instance) should not 'enable' them to export cheaply.
But similar countries like maybe Germany, France, UK, similar on-costs, so no tariffs.
No point having tariffs alone unless the manufacturing is there also, as USA is discovering...

Yes, but only on certain products to incubate local industries until they are competitive on the global market

I believe that it shouldn't the government bringing in imports at least, but rather its the people buying stuff only sold overseas and having it arrive at their houses

Yes, but only on a selective basis. Tariffs should be applied strategically, as overly broad tariffs can harm domestic industries, while a lack of protection can undermine them.

No, but have tariffs for retaliation where another country has breached trade agreement and tariffs should be a tool to protect certain strategic industries in energy, agriculture inputs and defence

Depending on what countries and depending on what they have done to Australia to breach our national Security and our nations trust and also depending on if other nations are doing the same thing and have tariffs on the particular country at hand
